Ajusco

Ajusco is an extinct volcano rising 3,930 meters above sea level, forming part of the Sierra de Ajusco-Chichinauhtzin range in southern Mexico City. Its slopes are covered with pine and oak forests that spread across wide areas.

Millions of years ago the volcano erupted and formed the present mountain, with large flows of lava shaping the surrounding land. By the 12th century people were using the summit for rituals and left behind pottery and tools.

Locals visit the area for weekend hikes and gatherings with family, often bringing food to enjoy in the surrounding pine forests. The mountain also supplies fresh water to neighborhoods below through underground springs and streams.

Several hiking trails lead to the summit and offer different difficulty levels for visitors who want to climb year-round. Weekends get crowded, so starting early in the morning is a good idea.

The summit has no typical crater because part of the mountain collapsed during an ancient eruption. On clear days you can see the entire metropolis spread out below from the highest point.
